Creating a Basic ZFS File System

ZFS administration has been designed with simplicity in mind. Among
the design goals is to reduce the number of commands needed to create a usable
file system. For example, when you create a new pool, a new ZFS file system
is created and mounted automatically.

The following example shows how to create a basic mirrored storage pool
named tank and a ZFS file system named tank in
one command. Assume that the whole disks /dev/dsk/c1t0d0 and /dev/dsk/c2t0d0 are available for use.

Typically, you want to create and organize a hierarchy of file systems
that matches your organizational needs. For information about creating a hierarchy
of ZFS file systems, see Creating a ZFS File System Hierarchy.
